Country music stars GARY ALLAN and Chris Young were forced to scrap appearances at the CMA Music Festival in Nashville, Tennessee on Thursday night (05Jun14) due to illness and injury.

Vocal issues forced Allan to pull the plug on his fan club party, while Young's hand injury kept him from a planned autograph signing event.

Reports suggest he cut his hand while cooking.

Young is still hoping to perform at the festival on Saturday night (07Jun14), but Allan's vocal problems are far more serious - the It Ain't the Whiskey singer has suffered similar issues in the past, and underwent surgery in 2010 to remove a polyp from his throat.
